## VS 2008 - Calculate Factorial From Number And Display In Textbox

Sep 14, 2009

So I need to get a button to take the number that a user enters into a textbox, calculate the factorial from that number, and display it in another textbox. I can't seem to get this to come out right.

Here's some of the code I've been playing with.
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
Function Factorial(ByVal txtFactorial As Decimal) As Decimal
If txtFactorial <= 1 Then
MessageBox.Show("Enter a number greater than 1")
Else
txtAnswer = Factorial(txtfactorial - 1)
End If
End Function

Now I have to just work out the code part. Can a function be under a button? I'm getting an error about that. I'm also getting an error about the txtAnswer=Factorial(txtfactorial-1) part of the code.

I have two money fields in a SQL database called TotalClaimed and PartialSettlementAmountRecd.They are declared as Decimals like so:

Public PartialSettlementAmountRecd As Decimal

## Progress Bar With Calculation?

Aug 25, 2011

I have an array of characters. Depending on the number selected (between 1 and 30), the program selects random characters and concatonates them into a string. Kind of like how I think a password generator would work.I want to update a progress bar to show how the operation is going, but I need to reserve 20% of the progress bar for some actions before this, and the last 10% for the actions that follow it. So there is 70% available to use. My question is:If I set the progress bar to 20% and do the following math: 70/NumOfChars, then use a for loop to add the result of this to the progress bar (pb+=result), why does the total progress NOT EQUAL 90%!

## Using Functions To Run Calculation?

Sep 11, 2011

I'm trying to work on code where I enter number of hours into a textbox (txtHours) and then EITHER you press a button (cmdPay) and then the income for the week is calculated and shows up in a second text box (txtPay) OR txtPay does the calculation itself, everytime a number is typed into txtHours.

Currently, my code is trying to do the former, because I have NO idea how to even approach the second option.My problem I am having with my code, is I don't know how to properly dim my parameters, since my "button_click" code keeps coming up with this error:Argument not specified for parameter...

Public Function PayTotal(ByVal cnthours As Double, ByVal standpay As Double, ByVal overpay As Double) As Double
cnthours = CDbl(txtHours.Text)

## Apply Calculation To A 2d Array?

Mar 23, 2012

I have a 2d array and I want to do a calculation on each element in the array and then return the index which results in the smallest value.

I have tried iterating through each element in the 2d array and running the calculation. If the calculated result is smaller than the currently stored minimum I set that to the minimum.

This works but it runs so slowly it makes the solution a non starter. It performs each calculation quickly but because of the number of elements in the array the calculation for the whole array is stupidly long.

## Array Calculation With CSV File?

Dec 4, 2011

I am trying to work with taking in and parsing CSV files. Right now I have it taking in and producing something like this:

The program loads the csv and copies the data into an array as such:

ReDim strarray(num_rows, num_cols)
For x = 0 To num_rows
strline = strlines(x).Split(",")

[Code]....

etc. I guess my main problem is trying to perform calculations to all values in a specific column. To start I am just trying to figure out how to isolate the columns and found that by using MsgBox(strarray(x, num_cols)) it will msgbox everything in the second column twice. I just want to try and understand how I can perform a basic calculation like multiply every value in the first column by 2 and every value in the second column one by 3.

## Calculation In Textbox - X Value For Column And Y For Row

Jun 12, 2009

In my form I have a text box for user to enter the number of column and row. And I also have a text box to enter the first X value and Y value. Now what I want to do is if user enter 2 for row and 10 for column then now I will have two rows with 10 column. The X value is for column and Y value is for row.

It will look like this
**********
**********

When the user enter the first X and Y value. For next X and Y value i must plus the original value with 2.54.
So my X1=TextBox1.Text
Y1=TextBox2.text
this values are input by user.

So
X2=TextBox1.text + 2.54
X3=X2 + 2.54.
and so onn. Same apply for Y
Let say user input are X=100 and Y=100
The value for first * is X= 100 and Y=100
Second *X=102.54 and Y= 100............. and so on
For 11th * X=10th *value + 2.54 Y= 100+2.54 and so on
The row and column is not same always it depends on user..
